MECHANICAL MOVEMENT.

SPECIFICATION forming part of Letters Patent No. 435,82,dated September 2, 1890.

Application filed April 1G, 1890. Serial No. 343,073. (No model.)

T0 all whom, t Naty concern:

Be it known that I, JAMES IIAYTON, of Salt Lake City, in the county of Salt Lake and Territory of Utah, have invented a new and Improved Mechanical Movement, of which the following is a full, clear, and exact description.

The invention relates to mechanical movements forconverti n g reciprocating motion into rotary motion, and its object is to provide a new and improved mechanical movement for said purpose, which is simple and durable in construction, very ci'ectivc and positive in operation, and transmits the power without any undue friction or lost motion, avoiding all dead-centers.

The invention consists of certain parts and details and combinations of the same, as will be hereinafter fully described, and then pointed out in the claim.

Reference is to bc had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the Iigures.

Figure l is a side elevation of the improvement in a central position. Figs. 2 and 3 are like views of the same in the end positions, and Fig. 4 is a transverse section of the same on the line Qc 0c of Fig. l.

The improved mechanical movement A is provided with a suitably-constructed baseplate B, adapted to be secured to the frame of the machine on which the mechanical movement is to be applied. On top of the baseplate B is arranged a longitudinally-extending guideway C, to the sides of which are secured upwardly-extending plates D, supporting at their upper ends a second guideway E, extending parallel to the guideway C. In the guideways C and E is fitted to slide longitudinally a frame F, provided with the two sides F and F2 and the ends F3 and F4, of which the latter are provided with heads F5 and F6, in one of which is secured a rod G by means of a pin II. The rod G is connected with the machinery the reciprocatingr motion of which is to be converted into rotary motion. The sides F and F2 lit into the guide- Ways E and C, respectively, and they are provided at their opposite edges with rack-teeth F7 and F2, respectively, three only in number, as shown in the drawings. The teeth F7 and F8 are adapted to be alternately engaged by teeth I, formed on a segmental wheel J, secured by its hub J on a transversely-extending shatt K, mounted to turn in suitable bearings L, and also provided with a Iiywheel N and the usual pulley O, adapted to be connected with suitable machiney to be driven. The inner edges of the ends F3 F4 of the frame are parallel with each other and at right angles to the u pperand lower toothed sides F F2. The said inner edges of the ends F3 F1 are centrally recessed, as shown at F9 F10, thereby forming a pair of shoulders F11 F12 and F13 F14 at the ends of the frame, the inner faces of each pair of shoulders lying in the same vertical plane. It will be noticed that the end edges J2 J3 of the toothed segment are radial to its axis and at an obtuse angle to cach other.

The operation is as follows: Then a reciprocatin g motion is imparted by the rod G to the frame F a continuous rotary motion is transmitted by the toothed segment J to the shaft K in the following manner: Vhen the trame F slides in the direction of the arrow a and is in the position shown in Fig. 1,then the middle tooth of the teeth on the side F stands in the middle of the segmental gearwheel J, and by the action of the latter it is turned in the direction of the arrow b. (See Fig. l.) lVhen the frame F nears the end of its stroke, the segmental gear-wheel assumes the position shown in Fig. 2-that is,thelast tooth on the side F is about to be disengaged from one end tooth of the segmental gearwheel J which, by its other end tooth, is about to be engaged by the first tooth of the other side F2. Vhen the frame in its movement to the right nears the end of the stroke, the parts will be in the positions shown in Fig. 2, and the shoulder F13 will engage the edge J3 of the segment J, and as the frame continues to move to the right will disconnect the last tooth at the upper end of the seg.

ment from the left-hand tooth of the upper series F7 and throw the edge J2 against the shoulder F14, so as to bring the last tooth at the lower end of said segment into position for action by the lowerleft-hand tooth Fsand just as the frame begins its return-stroke to the left. When the frame rea-ches the end of its left-hand stroke, the shoulder F12 will act IOO on the edge J 3 of the segmental gear J and throw its lower end tooth out of engagement With the lower right-hand tooth FB and its edge J2 against shoulder F, so that the top tooth I of the segment will be brought into position just as the frame again begins its right-hand stroke, and so on continuously. Thus it will be seen that a continuous rotary motion is imparted to the segmental gear- Wheel J and its shaft K by the reciprocating movement of the frame F in the guid eways C and E. It Will thus be seen that the reciprocatin g motion is converted into a rotary motion without the use of pitmen and crankarms and Without anyV lost motion Whatever. It will further be seen that the frame F, by means of the heads F5 and FG, can be readily attached to right or left handed machines, as the said heads are adapted to receive rod G coming from the right or left.

Having thus described my invention, whatI claim as new, and desire to secure by Letters Patent, is-

The hereindescribed mechanical movement, which consists in the upper and lower other, whereby when one of the frame-shoulders engages one of the end segments, edges, or shoulders the segment-tooth next thereto will be thrown out ot' engagement with the rack, and the other end, edge, or shoulder of the segment Will be thrown against the other one of the same pair of frame-shoulders to bring the adjacent gear-tooth into mesh with the adjacent end tooth of the opposite rack, substantially as set forth.

JAMES HAYTON.
